This subject requires fuller investigation, and it would be highly interesting if the Montpellier beds ~hould be found 1 ~o indicate a passage from the fossils of the Mwcene type to t 10 e of the older Pliocene. We are fully prepared for the discovery of such intermediate links, and we have endeavoured to provide a place for them in the classification proposed in the fifth chapter *. "' Page 57. CHAPTER XVI.

IN the present chapter we shall offer some observations on the alluviums and fresh-water formations of the Miocene era, and shall afterwards point out the countries in Europe where the volcanic rocks of the same period may be studied.

In order to account for the situation of these beds of rounded pebbles and sand, we must suppose that after the tertiary _strata g, covered by the basaltic lava f, had been disturbed and exposed to aqueous denudation, a valley was excavated, wherein the alluvium e accumulated, and in which the remain~ pf quadrupeds |
